Perfectly said. I love linux (and open source in general) -- it's been my daily desktop for over 2 decades, most of that with nothing but a terminal and web browser. And sometimes a terminal-based web-browser, at that. But my desire to learn, and retain the knowledge for something that I tweak once every couple of years is... low. I'm not afraid to dip into the command line on a router, if it's critical, I just don't *want* to.
